1231 & 1232 In-Situ Oxygen Probes

The Novatech 1231 and 1232 Oxygen Probes are Australian-made and embody the research and development of one of Australia’s premier research organisations, the CSIRO. The Novatech 1231 and 1232 probes are highly accurate, and have minimal drift (±1%). The Novatech in-situ probes are highly durable; choose the Novatech 1231 for analysing gases with temperatures below 900ºC (1650ºF) and the Novatech 1232 for temperatures ranging between 700°C and 1400°C (1290ºF to 2550ºF).

With a response time of less than 4 seconds, potentially hazardous situations such as those caused through the build-up of dangerous fuel-rich conditions can be avoided.

The probes are inserted into the flue, or other measuring point, and the threaded nipple (1231 has 1.5“ BSPT/NPT; 1232 has 3/4” BSPT/NPT) is screwed on to a mating socket welded to the process.

Connect the probe cable to the transmitter, and you are ready to measure and/or control the combustion process.

Certain processes, such as glass furnaces, ceramic furnaces or incinerators may contain highly corrosive particulate, abrasive or hostile compounds that will destroy any in-situ measuring device in short time.  By using a simple and inexpensive sample tube to extract a gas sample into a secondary sample chamber, accurate oxygen measurement can be achieved while reducing the exposure of the oxygen probe to the process environment.
